AC SENSE RELAY
Safe Power Sensing
The AC sense relay provides isolated power sensing and
control. It's more than just a relay in a box. It contains
an AC powered relay, circuit breaker, safety delay and
debounce circuits, and screw terminal dry-contact
outputs.
The relay coil driver senses AC power. The contacts
can controls either AC or DC devices. Whenever AC
power is within usable ranges (ie. 80-140VAC), the relay
is activated. When activated, the NO contact is closed
and the NC contacts is open. When power fails, this is
reversed: NC is closed, and NO is opened.
The output contacts are fully isolated, and can be
directly connected to a microcontroller for signalling, or they can be used to control a high power AC
or DC load. The two output contacts can control one
normally on device, one normally off device, or both
simultaneously.
Applications include:
• AC power failover systems
• Battery / solar backup systems
• . Building automation & home theater
• Alarms, power failure alert systems.
• Green power and energy conservation
Loads of up to 15 Amps total may be controlled.
Your imagination is the limit.
• A single 120V AC input input signal controls one
high-current SPDT relay. This relay signal switches a
single contact which provides either normally-on or
normally-off operation.
• Self-contained design eliminates dangerous high voltage wiring and safety hazards.
• Safety features include:
Magnetic isolation -- eliminates shock hazard
Relay hysteresis -- prevents relay chatter
De-bounce protection -- extends contact life
• The durable SPDT control relay is rated at 30/40A,
400,000 operations at 12A resistive. At no load, the
estimated lifetime is 5.3 million mechanical operations.
• A 15A thermal safety circuit breaker switch prevents
overloads and adds supplemental protection.
• Recommended operating ranges: AC input 90-120VAC.
Current 0-12A. 15A peak. Stranded wire only.
• Input connector: IEC 60320-1 C-8
• Output connector 3x screw terminals.
• Included cord: 24" IEC-C7 to 5-15 unpolarized.
• Indoor use only: -35F to 145F, 5-95% noncondensing.
